Hydrothermal microwave-assisted synthesis of Li3VO4 as an anode for lithium-ion battery

Li 3 VO 4 with various morphologies has been synthesized by a microwave-assisted hydrothermal method. It is shown that the crystal size and morphology of Li 3 VO 4 are determined by the type of solvent in the reaction solution and possible reasons of the solvent-type effect are discussed. Electroche...

Description
Summary:Li 3 VO 4 with various morphologies has been synthesized by a microwave-assisted hydrothermal method. It is shown that the crystal size and morphology of Li 3 VO 4 are determined by the type of solvent in the reaction solution and possible reasons of the solvent-type effect are discussed. Electrochemical studies of as-prepared Li 3 VO 4 as anode materials for Li-ion batteries demonstrate a clear influence of the materials’ morphology and surface properties on the electrochemical performance. Li 3 VO 4 nanocrystals with a porous structure exhibit an enhanced electrochemical activity with an initial discharge capacity of 163 mAh g −1 .
